I have been reading up on doing the LS1 electric fan conversion on my 2002 5.3L Avalanche and have not been able to figure out one part of the puzzle.
It is my understanding if I choose to go with LS1 fans and the Nelson Performance harness, I would need to get the PCM updated to activate the PIN for the fan.
What I am not clear on is if I get the fan activated in the PCM, is that change permanent? I am curious, questioning because I live in California and I don't want to fail smog when they hook up the OBDII.
A follow up question is regarding the DiabloSport inTune i-2030. I purchased one so that I can install a tune and then return to stock when I go in for the smog test. Can I activate the fans with that thing (still learning about it) using the stock tune and still pass smog? My concern is that I don't want to overhead the truck when I go for a smog test because the electric fans are not working.
I realize that the electric fans are not a big HP or MPG boost but I am doing it for fun and the experience of doing it.
Thanks.
